=== Satisfying EKNF === {{Main|Elementary key normal form}} The elementary key normal form (EKNF) falls strictly between 3NF and BCNF and is not much discussed in the literature. It is intended ''"to capture the salient qualities of both 3NF and BCNF"'' while avoiding the problems of both (namely, that 3NF is "too forgiving" and BCNF is "prone to computational complexity"). Since it is rarely mentioned in literature, it is not included in this example.
